Subject: SDL-1.2.5 patch to add ARB_multisample support
Attached is a patch I have written for SDL-1.2.5 that adds ARB_multisample
support. I only have the X11 and Win32 video patched. The Win32 patch also
adds support for WGL_ARB_pixel_format, as it was required for getting a
multisample capable pixel format. No additional GL header files are required
to compile on either platform (though you need an up-to-date glx.h for X11).
Requesting a multisample pixel format is made possible using
SDL_GL_SetAttribute with the two new SDL_GLattr's I've added
(SDL_GL_SAMPLE_BUFFERS and SDL_GL_SAMPLES). I've been using SDL in my
projects for quite a while now, so I am happy to contribute back to the
project. Now you can have and control FSAA in your SDL/GL apps at the
application level!
